INITIAL LUBRICATION
Although the engine was lubricated at the factory, it is important that you
lubricate the chassis before operation. Lightly grease the outside idler and
drive gears (marked “G” in Fig. 3 on page 7) to prevent them from squeaking.
Use light household oil and follow the lubrication points marked “L” in Fig. 2
on page 7. Do not over-oil. Use only a drop or two on each pivot point.
At this point, you are ready to put your engine on the track and begin running
it.
BASIC OPERATION
Throttle
– Throttle up the power to your track by either firmly pressing the
Direction button on your transformer or remote once or quickly dropping and
advancing the throttle to put the engine in forward.
OperationButtons
Use the operation buttons on your transformer or remote as described below.
Horn/Whistle
- To sound the horn, firmly press the Horn/Whistle button. The
horn will sound for as long as you continue to depress the button. It will stop
when you release the button.
Bell
- To sound the bell, firmly press and release the Bell button. To turn the
bell off, press and release the Bell button again. The bell will continue to ring
from the time your turn it on until you press and release the button again to
turn it off.
Direction
– Your train is programmed to start in neutral. To put the engine
into forward and then to change the direction of the train or to put it into
neutral, firmly press and release the Direction button on your transformer. Just
as you must stop your car between forward and reverse, this engine will not go
directly from forward to reverse; it goes into neutral between directions. If the
train has been moving forward, the first press of the Direction button will put
the train from forward into neutral, the second press into reverse, the third
press back into neutral, and the fourth back into forward. To prevent accidental
high-speed start-ups, this engine is programmed to restart in neutral each time
the track voltage is turned off for 10 seconds or more.

Speed Control:
M.T.H. engines equipped with Loco-Sound have speed control capabilities that
allow the engine to maintain a constant speed up and down grades and around
curves, much like an automobile cruise control. You can add or drop cars on
the run, and the engine will maintain the speed you set.
While the engine is programmed to start with the speed control feature
activated, you can opt to turn it off. This means the engine’s speed will fall as
it labors up a hill and increase as it travels downward. It is also affected by the
addition or releasing of cars while on the run.
To turn speed control on and off, put the engine in neutral, then press the
transformer’s Whistle button firmly but quickly one time then immediately
press the Bell button two times. Repeat the 1 whistle, 2 bells code to return it
to the other state. You will want to do this during the initial neutral upon
start-up if you ever couple this engine to another engine that is not equipped
with speed control to avoid damaging the motors in either engine. Each time
you shut down the engine completely, it will automatically turn speed control
on.
Feature to Be Activated:

ButtonCode:
1 Whistle, 2 Bells
1 Whistle, 3 Bells
Lock into a Directional State:
You can lock your engine into a directional state (forward, neutral, or reverse)
so that it will not change directions. To do this, put the engine into the
direction you want or into neutral, to lock it into neutral, run it at a very slow
speed (< 10 scale mph), and quickly but firmly press your remote’s Whistle
button once followed immediately by three presses of the Bell button. The
engine will not change direction (including going into neutral) until you repeat
the 1 whistle, 3 bells code to return the engine to its normal state.

Proto-Cast and Proto-Dispatch:
When used with the RailKing Remote Lock-on (sold separately),
Loco-Sound-equipped engines gain Proto-Cast
™and Proto-Dispatch™
features.
Proto-Cast:
This feature allows you to play audio recordings through your
engine’s speakers. You must supply the audio source (a small portable is
sufficient) and a male-to-male mini cable (1/8” plug, like that used for the
headset with a portable CD/tape player) to connect your audio source to the
remote lock-on. To use Proto-Cast, simply plug the mini-cable into your
audio source (usually into the headphone jack) and into the “Audio” port on
the right side of the remote lock-on and adjust the volume.
Proto-Dispatch:
This feature allows you to broadcast your own voice
through your engine’s speakers. You must supply the microphone and a mini
cable (1/8” plug, like that used for the headset with a portable CD/tape player)
to connect your microphone to the remote lock-on. To use Proto-Dispatch,
simply plug the mini-cable into the microphone and into the “Mic” port on the
left side of the remote lock-on and speak into the microphone.
When these features are in use, the locomotive’s own sounds (engine sounds
and bells, whistles, and horns) will be muted so that only the sounds you
broadcast will be heard. Because these two features are voice activated, there
will be a 10-15 second delay after you stop speaking into the microphone or
turn off the audio source before the engine sounds resume. To stop using the
feature and return to normal operation, unplug the cable from the lock-on jack.
If using parallel tracks with multiple Loco-Sound-equipped engines,
Proto-Cast and Proto-Dispatch transmissions from one track may be picked up
by the other nearby engines.
If you experience popping and interference, try cleaning the track with
denatured alcohol as described in the “Cleaning the Wheels, Tires and Track”
section of this booklet.
Note: M.T.H. does not recommend using Proto-Cast and Proto-Dispatch
at the same time.

MAINTENANCE
Lubrication and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
You should regularly lubricate the pickup rollers to prevent them from
squeaking. Use light household oil and follow the lubrication points marked
“L” in Fig. 2. Do not over oil. Use only a drop or two on each pivot point.
The locomotive’s internal gearing was greased at the factory and should not
need additional grease until after 50 hours of operation or one year, whichever
comes first. Follow the greasing instructions below. Note that in some tightly
packed engines you may need to move internal components temporarily in
order to access the gears.

1. Remove the screws from the chassis, as seen in Figure 3 on page 7, then lift
the body away from the chassis.
2. After removing the body shell, turn your engine upside down and remove
the two Phillips screws holding the pick-up roller to its truck. Lift pick-up
roller and unplug the wire.
3. Remove the single flathead screw in the adjacent pilot/trailing truck.
4. Remove the single Phillips screw that was hidden by the pick-up roller
before you removed it. Lift off the truck block and turn it over.
5. Remove the four Phillips screws from the truck block and pull apart.
6. Once the motor mount screw has been removed, pull the motor away from
the truck block and lightly coat the motor worm gear and bronze drive gear (in
the truck block) with grease.
7. Reassemble the truck and motor, being careful not to pinch any wires
between the truck block and motor mount.
8. Repeat the procedure for the other motor and truck
9. Reassemble the chassis and body, being careful that the wires are not caught
between the body and chassis, as this can lead to a short that may damage the
electronics beyond repair.
It is also a good idea to lubricate the outside truck block idler and drive gears
with grease occasionally. Add grease to the points marked with “G” in Figure
3.
Cleaning the Wheels, Tires and Track
Periodically check the locomotive wheels and pickups for dirt and buildup,
which can cause poor electrical contact and traction as well as prematurely
wear out the neoprene traction tires. Wheels and tires can be cleaned using
denatured alcohol (not rubbing alcohol), which can be found in home
improvement stores, applied with a cotton swab.
Occasional cleaning of the track will also help to ensure good electrical contact
and to prolong the life of your engine’s tires. To clean the track, use a clean rag
and denatured alcohol (not rubbing alcohol). Unplug the transformer and wipe
the rails of the track, turning the rag frequently to ensure that you are using
clean cloth on the rails.

Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on each
powered truck block. While these tires are extremely durable, you may need
to replace them at some point.
Replace the tires on only one end of the engine at a time.
To disassemble:
1. Remove the screws from the chassis, as seen in Figure 3 on page 7, then lift
the body away from the chassis.
2. After removing the body shell, turn your engine upside down and remove
the two Phillips screws holding the pick-up roller to its truck. Lift pick-up
roller and unplug the wire.
3. Remove the single flathead screw in the adjacent pilot/trailing truck.
4. Remove the single Phillips screw that was hidden by the pick-up roller
before you removed it. Lift off the truck block and turn it over.
5. Remove the four Phillips screws from the truck block and pull apart.
To replace the tire:
1. Make sure the old tire has been completely removed from the groove in the
drive wheel, using a razor blade or small flathead screwdriver to pry away any
remains.
2. Slip the new tire onto the wheel. You may find it useful to use two small
flathead screwdrivers to stretch the tire over the wheel.
3. If you twist the tire while stretching it over the wheel, you will need to
remove and reinstall the tire. Otherwise your engine will wobble while
operating.
4. Make sure the tire is fully seated inside the groove. Use a razor blade to
trim away any excess tire that doesn’t seat itself inside the groove properly.
Reassemble in the reverse order and replace the tires on the other end of the
engine.
One set of replacement tires is packaged with your model. Additional tires are
available directly from the M.T.H. Parts Department (phone: [phone];
